HESPERIA • Two Hesperia residents were arrested Wednesday night after San Bernardino County Sheriff’s deputies conducted a traffic stop and executed a search of a residence.

Authorities said two deputies from the Hesperia gang unit stopped a red Cadillac Deville near Main Street and Peach Avenue. The driver and sole occupant of the vehicle, later identified as Derek Haynes, 29, of Hesperia, told deputies that he was in possession of a concealed weapon.

Haynes, a convicted felon, was also in possession of a semi-automatic assault rifle, large capacity magazines, ammunition, body armor, brass knuckles, methamphetamine, digital scales and a hypodermic needle, according to a sheriff’s news release.

The vehicle, belonging to Hayne’s girlfriend, was found to be registered to an address shared by him and his girlfriend. Deputies obtained a search warrant for the residence located in the 11000 block of A Avenue in Hesperia.

Deputies from the Hesperia Station executed the search warrant at the address and made contact with Elizabeth Gauthier, 30, who was found to be in possession of methamphetamine.

Haynes is a documented gang member and was arrested and booked into the High Desert Detention Center on suspicion of numerous gang, drug and possession of firearm charges. He is on $100,000 bail and is scheduled to appear in court Friday afternoon.

Gauthier was also arrested and booked at the High Desert Detention Center on suspicion of possession of a controlled substance. She has been released on bail.
